Log message:
        Report rules which are never reduced by the parser: those hidden
        by conflicts.
        * src/LR0.c (save_reductions): Don't make the final state too
        different: save its reduction (accept) instead of having a state
        without any action (no shift or goto, no reduce).
        Note: the final state is now a ``regular'' state, i.e., the
        parsers now contain `reduce 0' as default reduction.
        Nevertheless, since they decide to `accept' when yystate =
        final_state, they still will not reduce rule 0.
        * src/print.c (print_actions, print_reduction): Adjust.
        * src/output.c (action_row): Track reduced rules.
        (token_actions): Report rules never reduced.
        * tests/conflicts.at, tests/regression.at: Adjust.
